Patent DE-4308509-A1 (DE)
Title: Heat exchanger for two-phase fluids
Inventor: POLOCZEK ERWIN DIPL ING
IPC: F25J3/00
Filed: 1993-03-17
Abstract: The aim is to improve a heat exchanger having a flow path for each of the fluids participating in the heat exchange, which heat exchanger has one or more passages formed by plates arranged at a spacing from one another, having a feed line and a discharge line for a first fluid, which are connected to one of the flow paths, and having a mixing device for a second fluid which is arranged in a second flow path. The second fluid is present in a gaseous and a liquid phase. This mixing device has separate feed lines for each of the two phases. In order in the case of high pressure loadability to guarantee uniform mixing and distribution of the two-phase fluid with a simple outlay on apparatus, it is proposed as mixing device in each passage of the second flow path to arrange small tubes, which proceed from the feed line for one of the two phases and lead to the mixing space, in the region through which the other one of the two phases flows to the mixing space.

Patent DE-4321314-A1 (DE)
Title: Apparatus for the loading and/or unloading of containers
Inventor: TIMMERBEIL KARL E
IPC: B65G67/20
Filed: 1993-06-26
Abstract: A loading apparatus for containers, with a roller conveyor having driving rollers and loading-material rollers, is illustrated and described. The driving rollers can be controlled, preferably automatically by a change in the direction of travel, between a free-wheel position and a position driving the loading-material rollers in the opposite direction, depending on the direction of travel of the apparatus. When the apparatus is used as a loading apparatus, the driving rollers free-wheel when the apparatus travels into the container and, when the direction of travel is reversed, are guided into the drive position, so that the loading material is retained in the container by the rotating loading-material rollers and is deposited by the apparatus while the latter is being drawn out of the container. When the apparatus is used as an unloading apparatus, the driving rollers are in the drive position when the apparatus travels into the container and guide the loading material to be picked up onto the apparatus in the opposite direction to the direction of advance of the latter. When the direction is reversed, the driving rollers commence free-wheeling, so that the loading material now rests on the stationary loading-material rollers while the loaded apparatus is travelling out of the container.

Patent DE-4329172-A1 (DE)
Inventor: LAUTENSCHLAGER WOLFGANG DIPL I
IPC: H04Q3/62
Filed: 1993-08-30
Abstract: Prior art: A supralocal virtual private network (VPNET) is formed by a number of private branch exchanges (PBX2, PBX3) or individual sets (E10) which, if necessary, communicate via public dial-up connections. The setting-up of the dial-up connections is initiated by dialling a service (VPN). Technical problem: The entire supralocal private network (VPNET) should act like one network for callers (C) on the public network (PUBNET). Basic concept: The service supports the switching of calls both from inside and outside the private network (VPNET), but allocates different tariffing attributes to the connections. Solution: IN service which transfers both calls between private branch changes (PBX1, PBX2) of a private network (VPNET) and from outside by means of a private numbering plan but, in doing so, initiates different tariffing. Advantages:     - Uniform company call number. - The same call number when moving from the area of one private branch exchange to that of another one. - Uniform company numbering plan also valid for calls from outside.     <IMAGE>
